Exhilaration (7)
I believe the answer is:
elation
'exhilaration' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for elation that I've seen before include "exhibits successful pride" , "Feeling of delight, joy" , "Ecstasy -- toenail (anag)" , "Feeling of delight or pride" , "Delight, ecstasy" .)
